Parachuting has become progressively a very popular recreational sports in foreign developed nations, and subsequently injury caused by it is getting more frighten and sometimes severe. Authors in this study clinically analysed 306 cases of parachuting injury who were treated at the department of orthopaedic sugery, C.A.F.G.H. during 3 years period from March, 19xx to February, 19 XX. There results were as followings: l. Of 306 cases, 268 had fracture, 38 soft tissue injuries. 2. Of 268 fracture cases, 208 cases had injuries in the lower extremity, 48 cases in trunk, 15 cases in upper extremity. 3. The most common associated injury was the head injury (26%). 4. The most common injured site was ankle and foot (57.5%), the next spine and pelvis (16.9%). 5. Through this study, it is said that parachuting is a dangerous sports, and the injury caused by parachuting may be largely preventable, if with adequate practical instruction, coaching and wearing protective garments.

4.A Case of Bilateral Congenital Arteriovenous Communication.
Journal of the Korean Ophthalmological Society 1996;37(7):1218-1223
Congenital arteriovenous(AV) communications of retinal circulation are rare developmental anomalies, exsisting alone or in association with ipsilateral vascular anomalies of the mid brain, cranial sinuses and skin. These are usually unilateral. We report a case of bilateral congenital arteriovenous communication. The right eye showed group III arteriovenous communication of retina with vitreous hemorrhage. The left eye showed group II arteriovenous communication combined with group I.

5.Surgical Result of Unilateral Medial Retus Recession and Lateral Retus Resection in Esotropia.
Journal of the Korean Ophthalmological Society 1996;37(9):1513-1520
To determine the effectiveness of unilateral medical rectus recession and lateral rectus resection in esotropia, surgical outcome was reviewed. We excluded paralytic strabismus, refractive esotropia and nonrefractive esotropia with high AC/A. Of 128 cases, 60 cases were male, 68 cases were female. At the amount of surgery, age distribution was from 11 month to 55 years. Preoperative angle of deviation was from 12 delta to 95 delta. We treated the patients with varying amount of unilateral medial rectus recession from 2.5mm to 8mm and unilateral lateral rectus resection from 2.5mm to 10mm. Following 31 months in average, 102(79.69%) showed successful alignment(orthporia +/-10 delta). The average amount of correction amount was 30.42 delta.

The purpose of this study was to investigate the effects of articular immobilization-induced hindlimb skeletal muscle atrophy on the autophosphorylation of the insulin receptor tyrosine kinase in rats. Rats were divided control, and knee and ankle joint immobilized groups. The experiments were performed on the 3rd, 7th, and 21st day after the immobilization. immobilization was induced by k-wire fixation in knee and ankle joint. The ratio of soleus muscle weight to body weight was decreased in proportion to the duration of the immobilization. The glycogen content of the soleus muscle was decreased significantly (p<0.01) at the 7th day, but this value was recovered to 65% of control at the 21st day after the immobilization. The insulin bindings at various concentrations of insulin to wheat-germ agglutinin purified insulin receptor from red gastrocnemius muscle at the 7th day after immobilization were not changed compared to control. The autophosphorylation of the insulin receptor tyrosine kinase with 10-8 and 10-7 M insulin concentration at the 7th day after immobilization was decreased compared to control. In conclusion, above results showed that insulin resistance of immobilized rat hindlimb skeletal muscle was arised from defect of autophosphorylation of the insulin receptor tyrosine kinase in part.

OBJECTIVES: This study was designed to investigate the prevalence of depressive symptoms in patients with breast cancer and to identify demographic variables and clinical characteristics impact on depressive symptoms and health related quality of life in patients with breast cancer in a university hospital. METHODS: Fourty-one patients with breast cancer were selected, who had visited the department of General surgery of the Wonkwang University hospital with a diagnosis of breast cancer regularly during the period November, 2010-May, 2011. All of subjects were evaluated for the depression, anxiety and the health related quality of life with Beck Depression Inventory(BDI), anxiety subscale of Personality Assessment Inventory(PAI) and Short-Form 36 Health Survey-Korean version(SF-36-K). Patients were divided into depressive symptoms and non-depressive symptoms group according to the BDI score. We compared SF-36-K between two groups, and analized multiple regression with depression and health related quality of life as criterion variables and demographic and clinical characteristics. RESULTS: The prevalence of depression in patients with breast cancer in a University hospital was 36.4%. Compared to the non-depression, depressed patients with breast cancer appeared significantly lower mean scores on six subscales in SF-36-K : Physical function(p<.01), Role-physical(p<.001), General health(p<.05), Social function(p<.001), Role-emotional(p<.001) and Mental health(p<.001). But there was no significant difference between two groups in Vitality and Bodily pain. Anxiety, level of education and presence of enforcement of chemotherapy(63.6%) were significant explanation variables for depressive symptoms. And type of surgery and age (55.8%) were significant explanation variables for health related quality of life. CONCLUSIONS: The prevalence of depressive symptoms in patients with breast cancer in a University hospital was 36%. The depressive symptoms had not only negative impact on the health related quality of life but also important explanation variable for health related quality of life. These results suggest that depressive symptoms in patients with breast cancer should be evaluated and treated for improving patient's health related quality of life.

10.Surgical Findings to Differentiate Between Facial Nerve Schwannoma and Vestibular Schwannoma.
Clinical and Experimental Otorhinolaryngology 2014;7(3):157-159
OBJECTIVES: Facial nerve schwannomas may be misdiagnosed as vestibular schwannomas (VSs) if the tumor is confined to the internal auditory canal (IAC) without involvement the geniculated ganglion or labyrinthine segment of facial nerve. Because facial nerve schwannomas may be misdiagnosed as VSs, we investigated the differences between the two. METHODS: The study included 187 patients with a preoperative diagnosis of VS. Of these, six were diagnosed with facial nerve schwannomas during surgery. We reviewed the preoperative evaluations and surgical findings of facial nerve schwannomas mimicking VSs. RESULTS: No useful preoperative predictors are available for facial nerve schwannomas mimicking VSs. Facial nerve schwannomas are usually confined to the IAC. After opening the dura of the IAC, a facial nerve schwannoma can be diagnosed after identifying a normal-appearing nerve located lateral to the tumor. When this was the case, we performed facial nerve preservation surgery or decompression. CONCLUSION: Facial nerve schwannomas can be differentiated from VSs by identifying specific findings during surgery.
